🔒 A recent Hudson Rock report reveals a threat actor known as Zestix (aka Sentap) harvested credentials from infostealer logs and accessed cloud file-sharing services such as ShareFile, Nextcloud and OwnCloud because affected organizations did not enforce multi-factor authentication. The actor exfiltrated and auctioned highly sensitive corporate and customer data. The incidents underscore persistent failures in credential hygiene, long-lived stolen credentials and the necessity of MFA and session invalidation.

🔐 A threat actor known as Zestix is offering corporate data reportedly stolen from dozens of companies after breaching ShareFile, Nextcloud, and OwnCloud instances. Hudson Rock links initial access to credentials harvested by infostealers such as RedLine, Lumma, and Vidar, often delivered via malvertising or ClickFix campaigns. Many affected accounts lacked multi-factor authentication, enabling unauthorized access and large-scale data exfiltration.

⚠️ Fortinet warned on December 24, 2025 that attackers are actively abusing a five‑year‑old FortiOS SSL VPN flaw, CVE-2020-12812 (CVSS 5.2), to bypass two‑factor authentication under specific configurations. The issue stems from inconsistent case sensitivity between FortiGate local users and LDAP directories: if a username's case does not exactly match the local entry, FortiGate may fall back to LDAP and accept credentials without 2FA. Fortinet reiterated prior patches and published configuration mitigations and commands to disable username case sensitivity, and advised customers to contact support and reset credentials if unauthorized 2FA bypass is detected.

🔒 CERN manages cybersecurity across a globally distributed research community by prioritizing risk adaptation over one-size-fits-all controls. CISO Stefan Lüders frames security as a sociological challenge—measures must be explained and adapted so academic freedom and research workflows remain viable while defending against threats from script kiddies to ransomware and espionage. With roughly 200,000 devices and extensive BYOD, CERN relies on defense-in-depth, network monitoring, segmentation for legacy and IoT systems, and mandated protections such as MFA. Governance is being formalized through audits and standards while preserving operational flexibility.

🔐 Small and medium-sized businesses became the primary target of data breaches in 2025, as attackers shifted focus from well-defended large enterprises to higher-volume attacks against smaller organizations. High-profile incidents at Tracelo, PhoneMondo, and SkilloVilla exposed millions of customer records—predominantly names and contact information—raising the risk of follow-on phishing and fraud. To reduce breach risk in 2026, adopt two-factor authentication, enforce the principle of least privilege for access control, and centralize credentials with a secure password manager. These steps are practical, cost-effective, and scalable for SMBs.

🔐 Fortinet has observed active abuse of FG-IR-19-283 (CVE-2020-12812) in environments where FortiGate and LDAP username case handling differ. In these configurations, a username entered with any case variation that does not exactly match the local FortiGate entry can bypass local 2FA and instead authenticate via an LDAP group fallback. Administrators should enable the appropriate username sensitivity setting or remove unnecessary secondary LDAP groups to block this bypass.

🔒 Amazon WorkSpaces Secure Browser now supports Web Authentication (WebAuthn) redirection, enabling users to authenticate to websites from within remote browser sessions using local FIDO2 security keys, passkeys, and platform authenticators like Windows Hello or Touch ID. This capability works with Chromium‑based local browsers such as Google Chrome 136+ and Microsoft Edge 137+, but not with Safari or Firefox. Administrators must enable WebAuthn redirection in the Secure Browser portal and configure the WebAuthenticationRemoteDesktopAllowedOrigins policy on local browsers to allow secure token forwarding. The feature is available at no additional cost in all supported regions.

🔒 Security researchers observed a coordinated credential-stuffing campaign targeting Cisco SSL VPN and Palo Alto Networks GlobalProtect portals over a two-day span in mid-December. GreyNoise reported millions of automated login sessions from more than 10,000 unique IPs, using a consistent TCP fingerprint and a Firefox-like user agent. The activity did not exploit software flaws but instead relied on large-scale username/password probes. Analysts urged enforcing strong passwords and MFA, auditing exposed edge devices, and leveraging threat-intel blocklists to filter malicious traffic.

🔐 An automated password-spraying campaign is targeting multiple VPN platforms, with credential-based attacks observed against Palo Alto Networks GlobalProtect portals and Cisco SSL VPN gateways. GreyNoise recorded login attempts peaking at 1.7 million over 16 hours from more than 10,000 unique IPs, largely originating from the 3xK GmbH hosting space. The actor reused common username/password combinations and used an unusual Firefox user agent, indicating scripted credential probing rather than exploitation. Administrators are advised to enforce strong passwords, enable MFA, audit appliances, and block known malicious IPs.

🔐 The EU's NIS2 Directive requires organizations in critical sectors to strengthen identity and access controls, with Article 21 explicitly calling for access policies and practical protections. Modern password hygiene favours long passphrases (e.g., 15+ characters), breach screening, and avoiding routine rotations unless compromise is suspected, alongside user-friendly measures like password managers. While NIS2 doesn't always explicitly mandate MFA, national guidance and ENISA expect phishing‑resistant MFA for privileged and critical accounts.

🔒 Sponsored content from Token presents wireless biometric passwordless authentication as a way to transform MFA from a persistent cost center into a measurable productivity gain. By replacing passwords and authenticator apps with proximity-bound biometric hardware such as Token Ring and Token BioStick, Token says average login time falls from 22 seconds to 2 seconds. The vendor asserts this yields roughly $1,466.67 per employee per year in recovered productivity while also reducing password resets and blocking phishing, session relay, and social-engineering attacks.

🔒 Cyber hygiene is presented as an essential, routine set of practices to reduce digital risk and protect personal data. The article gives targeted, practical advice for three audiences: beginners (use a password manager, create long random passwords and enable MFA), intermediate users (prioritize patch management, remove unused extensions, secure home routers and IoT, and use VPNs), and cybersecurity professionals (model good behavior and build a security-aware culture). Small, regular actions can greatly reduce exposure and improve resilience.

🔒Four newly documented phishing kits — BlackForce, GhostFrame, InboxPrime AI, and Spiderman — enable large-scale credential theft and advanced MFA bypass techniques. BlackForce (first seen August 2025) uses Man‑in‑the‑Browser (MitB) capabilities to capture OTPs and exfiltrate data to Telegram/C2 panels, while GhostFrame hides phishing pages inside iframes. InboxPrime AI automates high-quality mass mailings with generative assistance, and Spiderman offers full-stack banking replicas with ISP and geofence filtering. Researchers warn these kits lower the bar for attackers and recommend layered defenses including phishing-resistant MFA, strong email validation, anomaly detection, and user training.

🔒 Modern water and wastewater systems face accelerating cyber threats as utilities adopt remote sensors, cloud telemetry, and integrated SCADA. Critical safeguards—multi-factor authentication, network segmentation, and unified IT/OT visibility—are often missing, increasing risk from nation-state actors and ransomware. Utilities should prioritize comprehensive asset inventories, containment architectures, anomaly detection (e.g., FortiNDR, FortiSIEM), and regularly tested recovery plans to meet rising federal expectations.

📷 South Korean authorities arrested four suspects after roughly 120,000 internet-connected IP cameras in homes and businesses were breached and sexually explicit footage was sold on an overseas adult site. Investigators indicate attackers likely exploited weak or default credentials and unpatched device software. Owners should replace factory passwords, use unique credentials and enable two-factor authentication; consider a reputable password manager such as Kaspersky Password Manager to generate and store strong, random passwords and one-time codes.

🔔 The Identity Theft Resource Center's 2025 Business Impact Report found that 81% of US small businesses experienced a data or security breach in the past year, and 38% raised prices as a result. Respondents attributed 41% of incidents to AI-enabled attacks, while external actors and malicious insiders were cited by 43% and 42% respectively. The ITRC warns that adoption of protections such as MFA is falling and advises SMBs to focus on people, process and technology defenses including out-of-band verification and AI-driven detection tools.

🔒 Retailers face concentrated credential risk during holiday peaks as bot-driven fraud, credential stuffing and pre-staged automated attacks target logins, payment tokens and loyalty balances. Effective defenses combine adaptive MFA, bot management, rate limiting and credential-stuffing detection to stop automation without harming checkout conversion. Strong controls for staff and third parties, plus tested failovers and tools like Specops Password Policy to block compromised passwords, reduce blast radius and protect revenue.

🔐 Beginning December 2, a campaign using more than 7,000 IPs from German host 3xK GmbH (AS200373) carried out brute-force login attempts against Palo Alto GlobalProtect portals and soon pivoted to scanning SonicWall SonicOS API endpoints. GreyNoise links the activity to three recurring client fingerprints seen in prior scans and to earlier campaigns that generated millions of HTTP sessions. Organizations should monitor authentication velocity and failures, block implicated IPs and fingerprints, and enforce MFA to reduce credential abuse.

🔒 In this Deputy CISO blog, Damon Becknel, Microsoft’s VP and Deputy CISO for Regulated Industries, outlines four immediate priorities organizations should act on now. He emphasizes reinforcing essential cyber hygiene—accurate asset inventories, network segmentation, timely patching, MFA, EDR, and proxying email and web traffic—as the most effective means to reduce common intrusions. Becknel also urges adoption of modern standards like phishing-resistant MFA, secure DNS and DMARC, deployment of fingerprinting to track bad actors, and active cross-industry collaboration to share threat signals and raise the cost of attack.

🛡️ The hiring pipeline is being exploited by sophisticated threat actors who create fake personas—complete with fabricated resumes, AI-generated videos, and stolen identities—to secure privileged remote roles inside organizations. Once hired these imposters can exfiltrate data, plant backdoors, or extort employers, making the risk especially acute for MSPs that manage multiple clients. Strengthening HR verification, staged access provisioning, hardware-based MFA, network segmentation, and ongoing security awareness training are essential to mitigate this insider impersonation threat.
